Abstract

Abstract A foldable mechanic's creeper that it particularly compact and easy to store includes hinge-connected panel members, each having a panel portion and a peripheral flange portion, the panel members being movable between an open position and a closed position in which the flange portions are in edge-contact for forming a closed container. In the open position, the panel members are rollingly supported on casters for carrying a user in a supine position, the user's head being supported on a padded support that is removably mounted in horizontally spaced relation to one of the panel members. With the panel members in the closed psition, the head support and the casters can be safely enclosed within the container that is formed by the panel members. An extensible mount for the head support serves as a carrying handle for the folded creeper.

Claim 9
Dependent Claim 22 words
The apparatus of claim 6 wherein the hinge member is a flexible member formed integrally with the first and second panel members.
Claim 10
Dependent Claim 76 words
The apparatus of- claim 1, further comprising: (a) handle means movably engaging the first panel member for carrying the creeper with the panel members in the closed position, the handle means having extended and retracted positions, (b) wherein the means for supportively connecting the head support member comprises means for supporting the head support member by the handle means in horizontally spaced relation to the first panel member with the handle means in the extended position.
Claim 11
Dependent Claim 47 words
The apparatus of claim 9 wherein the head support member is removably connected to the handle means, the panel members forming locating means for storing the head support member when the panel members are in the closed position and the handle means is in the retracted position.
Claim 12
Dependent Claim 54 words
The apparatus of claim 9 wherein the handle means comprises a U-shaped member-having spaced apart leg portions and a connecting handle portion, the leg portions axially engaging the first panel member, the head support member having a U-shaped groove formed therein for engaging the handle portion and the leg portions of the handle member.
Claim 13
Dependent Claim 17 words
